Application filed October 7, 1908. Serial No. 456, 20,

To all whom'it may concern:

' Be it known that I, GEORGE ELLIOT PERRY, a' citizen of the UnitedStates, residing at Chicago, 'in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Stamps,of which the following is a specification.

My invention relates to improvements in stamps wherein the impressionparts are automatically variable, and in some of its features it hasreference particularly to time stamps.

Inthe drawings I have shown an. embodiment of my invention in a pivotedarm time stamp, in which the impression members are carried in a head atthe extremity of anarm or movable stamping element, pivoted to a basestructure which provides a platen againstwhich the impression headoperates vwhendepressed, and to tlns class of stamps my present,invention particularly relates,

although some of its features are applicable to other types of stampingmechanisms.-

.n In the'drawings:MFigurc l-is a longitudiem- 'body ing;my invention,showing the variable impression movement in-elevation;- Fig. 2 is theplan view'with the swinging arm in section; Fig. 3 is a horizontalsection on nal, vertical section'through a stamp line *33 of Fig. 4;Fig. 4 is a vertical section. on line 44 of Fig. 3; Fig. 5 is asectionon line 5-5 of Fig. 3; Fig. 6 is .a vertical section on line 6-6 of Fig.1; 7 is a detail of a shaft; Figs.- 8 and 9 are sections thereof onlines 88 and 9- -9;

. Figs. '10 andll are side and end views of a pinion segment shown onFig.- l, and; Fig, 12 is a: detail showing the means of securing theimpact receiving cushion to the movable arm. 4

In the embodiment of my invention shown I provide a hollow base 20,arranged to receive-and conceal the motor devices for actuatingt-heimpresslon-varying means,

and carrying the stationary member or platen for coaction with theimpression parts, said base having connected thereto for verticallyoscillating movement a movable stamping element 21 pivoting on ahorizontal aXis'and carrying in its head or free endthe impressionparts, arranged to cooperate with the platen to effect an imits forwardend'with a platen pad 22, at.

pression vupon any interposed article when the arm isdepressed. The base20 is preferably ahollow casting, provided adjacent its rear endnarrowed into a vertical neck 23, above which projects vertical sidelugs 24, receiving pivot screws 25, and extending therea-bove. The motormechanism is inclosed within the hollow base 20, and as "generallyindicated at 26 may conveniently be an electro-magnet, although anyother available 'form of motor mechanism may be substituted withoutchange of many of the features of my invention.

For supporting the motor mechanism, of

whatever character desired, I provide a novel and advantageousarrangement, tothis selves retained against displacement by screws 30inserted vertically into the posts '27, close beside'therods 29, 29.with their heads so closing the recesses 28 as to preventescape of therods 29, 29 therefrom In the specific construction shown the rods 29,29maybe of brass or other diamagnetic material, passing through themagnetic polepieces 31 of an electro-magnet constituting theelectro-motive part of the motor 26. The rod 29 likewise affords supportto abrass plate 32 carrying an armature 33, and provided withan arm 34,which constitutes the power lever for actuating the lmpression-varylngdevices, said lever being preferably constructed with a later allyprojecting pivot pin 35, having a head 36, all formed of sheetmetal, asbest shown inFig. 6 I l The'bottom of the base is preferably coveredwith a plate 37, which may, if desired, be made in two parts,h-inged'together as at- 38, that'the forwardmost part indicatedspecifically as 37 may be opened downward to expose the' interior of thebase, and said hinged portion 37' may conveniently be provided with areceptacle, 39, for. reception of extra parts of the machine, ribbonsand the like. a

The arm 21 is a thin shell open throughout on its lower side, providinga head portion 40, a rearwardly extending neck 41,

at its rearward, entremitycurved downward screws 25, for verticaloscillation. Th u ward movement of arm 21 is normally limited ,by stop46 mounted on aleaf spring 17-, secured to the base member andinterposed between the rear wall of the basethroat 23' and theneck 41.By throwing the stop 4-6 outward-against the tension of its spring47,,the range of upward movement of arm-21 is greatly enhanced so thatitmay be thrown back for the examination of the parts presented on itslower surface. Normally the arm 21 stands in a position limited by stoplfi under the tension of an expansible spring 48, at one end connectedto a clip 49, within the neck 11, and at its other end to a cross rod50, in the lugs 24 above the pivot screws 25.

-Upon the top of the head 40, I detachably mount an impact cushion forreceiving the blow of the operators hand, said cushion comprising aresilient convex pad 51, of rubber, or the like, carried by a plate 52,having suitably-shaped. peripheral walls 53, toreceive and hold the pad51, said plate 52, having made therein a suitable button-hole slot 54-to receive a headed pin 55-mounted on the head of the moving element 21.Said plate 52 is provided with latching means for yieldingly resistingdisengagement of the pin from the smaller end of the slot, such meansbeing herein shown as small studs 56. v Thus the cushion may he slippedonvafter all the rest of thestructure is complete, so that the newappearance of the rubber may not be destroyed by handling-in the courseof manufacture.

The impression wheel movement and the inking devices therefor" I mountin a frame 60 comprising side plates 61 and61 connected by cross posts62 secured in head as byscrews 63, and further connected as by thebottom members 64, 64 carrying fixed impression surfaces 65 and 65,suitably separated to leave therebetween a space 66 for the operation ofthe changeable impression wheels or rosettes. A shaft 67 directly abovesuch opening carries the independently rotatable impression wheels orrosettes 68 68*, 68, 58 68*, se 68 and ss bearing respectively indiciaof units minutes; tens of minutes; hours; a. m. and p. m.; units days;tens of days; months; and years, and whereof all save the months and theyears wheels are automatically movable. Each rose-tte 68*, 68, etc., hassuitably connected therewith a ratchet as at 69 69 etc., provided withteeth 70 corresponding in number with the impression surfaces on therosette, separated by spaces 71, generally shallow, except those spacesin proper relation to the last impression of the series or succession ofimpressions on the rosette, which said final spaces are relatively deepas shown at 72. Preferably, further, the spaces and teeth are generallyshaped to form a gear as well-as a ratchet, so that the same part mayserve for receiving a ratchet device and imparting a gear transmission.

\Vith each such ratchet 69 is associated a dead or holding pawl,arranged to yield to permit forward movement of the ratchet, anddisposed so. that when the position of the ratchet is controlled solelyby such pawl, it invariably positions the ratchet to bring a printingsurface of the rosette into proper printing position within the orifice66. These dead pawls 73 (differentiated by exponents corresponding withthose of their respective ratchets) are mounted for independentmovement. upon an arbor 74, and each is pressed toward its ratchet by anindependent spring 75, which may suitably be a leaf spring bearing atits free end against the frame Jost 62. Each such pawl 73 has its nose76 so shaped for'cooperation with the spaces 71 of the correspondingratchet, as to engage the teeth on both sides of such spaces and thusdefinitely to position the rosettewith a printing or impression surfacein proper register with the orifice 66'. This feature is important ininsuring proper alinement of the printing parts, and also as giving thepawl the capability of automatirally bringing the ratchet back to properposition if thrown slightly beyond such. po-,

sition by the action of the ratchet moving part. 'Such overthrow of someof the ratchets occurs in the normal operation of the machine,'for thereason that some of the ratohets have only ten teeth while others havetwelve and the range of, movement of the ratchet-moving mechanism, to besufficient -to properly move the ten toothed ratchets, constitutes anoverthrowing movement of the twelve-toothed]ratchets. The

"ratchets' may,'however, be only ten-toothed or twelve-toothed,byproviding impression symbolsupon. the rosettes'as follows; units,

minutes rosette, Zfigureszero to '9'; tens of minutes, rosette,v figureszeroto 5, two occan'renres;,heur's rosette, one to twelve a. In". and p.m. rosette, six-occurrerices of the symbols";' unitsqdays rosette, zerotot); tens of'da.ys rosette, ablankand numerals 1, 2

and 3;,three' occurrences; months rosette,

twelve indications, years rosette, 10 or 12, as

desired.

The l1ve 'ormovinggpawls for the several automatically movablev.rosettes, are ar-' rangeddn novel fashion for movement from a singleprimef nioiver for positive oscilla tion about one center eccentric tothe ratchets to bring the active pawls into and out of engagement.witlrtheir ratchets, andpositive oscillation about another center, 00-incident with the axis of the ratchets to through the yoke and througha' slot 82 in the frame member 61. said slot being con- In said y'oke iscentric with the rosette arbor (57. The shaft shorter each by the depthof a space 71 of a ratchet, as best shown in Fig. 3. Thus it Wlll beunderstood that oscillation of the comb about the shaft 81 as a centerthrows the pawls toward or from engagement witn their ratchets, whileoscillation of the carr er 80 about the shaft 67 as a center, while .thepawls, are in engagement with their ratchets, advances the ratchets andtheir corresponding rosettes rotarily, It will I further be apparentthat only when one ratchet is in such position that its deep space 72may receive its pawl'may the next succeedmg ratchet receive itscorresponding pawl,-as the engagement of any one pawl with a space ofnormal depth inits ratchet withholds'the next succeeding pawl fromoperative engagement with its corresponding ratchet. Thus only when onerosette .moves from position for printingthe last impression of itssequence, to commence its sequence afresh does the next rosette advanceonetooth.

As the oscillation of the pawl comb about its shaft 81 must occur whenthe yoke 80 is in one of its terminal positions, I provide means for"yieldingly resisting movement of said yoke from either terminalposition, and definitely locating its terminal positions,

preferably as follows :-A side member of the yoke 80 is provided with anarcuate surface 86, terminatino' in two-notches or de-. pressions, 87,and. Sr beyond which are inelined shoulders 88 and 88; and a frictionpawl 89, provided preferably with a rounded nose 90, is arranged to actupon the'described surfaces, under the influence of a spring 91pressingit inward, so that when the noseof the pawl is seated in eitherrecess 87 or 87 it resists movement of the yoke from such position, andif the yoke be moved to bring one of the, inclined shoul ders 88 or 88beneath the nose 90 the pawl 89 will act as soon as the moving force isremoved from the yoke 80, to bring the yoke back until the nose 90 isproperly seated in the appropriate notch 87 or 87. For connecting thelive pawl structure with the armature 34'of the electro-magnet, 1provide a curved'arm 92 having a bifurcated end 93 straddling theintegral pivot pin 35 of the armature lever'3 1, and at its other endextending forward into the frame 60, and there provided with a slot 94,providing an interior rack 95,. engaging a small pinion 96,. preferablymade integral with a shaft 97 (shown in Figs. 7 and 9) which findsbearing in the frame 60 and extends beyond theside member 61; The shaft97 carries 1 19 a a a a disk 98, to which is pivotally connected, as at99, a link 100, having in its lower end a slot 101; provided with;r'aekteeth 102'on one side for engagement with a pinion segment 108,mounted on the projecting end of shaft 81. For normally holding the arm92 in rearward position at its other limit of movement from that shownthroughout the present drawings, and with the armature 33 retracted fromits magnet, a suitable spring is provided, the construction illustratedproviding a spring 104 coiled around the frame post 62, and engaging asuitable op'ening105, in the arm 92. p

The arrangement of rack 95 and pinion 96 is such that the withdrawal ofthe arm 92 from theposition shown in the drawing to its rearmo stposition under the influence of spring 10st,,rotates the disk98 to bringits pivot pin 99 somewhat beyond the line of centers of shafts 81 and97, so that withdrawal of the .arm '92 from the position shown willcause in general a raising of the link 100, followed by ii slightterminal depression thereof. During such movement the link acts throughthe aositive earin connections 102, 108; to oscillate the shaft 81 tothrow the pawls 35 into engagement with the active ratchetsio, suchextent as the position of the ratchets will permit, and then when theshaft 81 islocked against further movement to draw the yoke 80 bodilyupward abovethe shaft (37 as a ce ntel until the other normal limit ofmovement of the yoke has been reached or slightly passed when thepivotal connection 99 will have reached the line of centers of theshafts 81 and 97, such oscillation of the pawl carrying yoke causing theactive pawls to advance their ratchets a full step or a little more.\Vhcn the pivot point 99 of the link passes the line of centersaforesaid. the slight continued movement gives the link 100 an upwardmotion sufiicient to cause the rack 100 to throw the segment l03 throughthe partial rotation necessary" to withdraw the pawls 85 from the activeratchets leavjust itself to its normal limit of movement.

The opposite movement of the arm 92, that is from rearmost position tothe forward position shown obviously causes the pawls 85 the point 99approaches the line of'centcrs;

then to retract as the pawl-controlling segment 103 is rotated to theextent allowed by slot 101 by the initial downward movement, and thenthe yoke 80 is positively forced down fromits raised position to theposition shown in the drawings. Thus from .-.E

- to dip momentarily toward their ratchets as a single part or primemover I supply positive motion to the pawlsto oscillate them abouttheirfshaft center, for engagement and disengagement, and'to oscillatethem changed by getting access to the rosettes through the aperture 66,this method is not convenient and I preferably provide in conjunctionwith the impression rosettes-which, of course, bear 'negatir e printingcharacters, set of setting and display rosettes easily accessible andbearing positive or directreading symbols. To this end I provide in thefront of the frame an arbor 105 and upon such arbor 105 I mount a seriesof disks 106*, etc., bearing direct reading characters correspondingwith the printing characters upon the companion printing rosettes, andwith each such display wheel 106, etc, I connect'a pinion-107 etc., forgearing with the corresponding 'printing" rosette. herever it isconvenient I make the gear 107 mesh directly with. the ratchet 69 of thecorresponding rosette, thus making some such parts 69 perform thefunctions of a ratchet, a gear, and a self-alining device (whencooperating with the dead pawls 73) andthis arrangement I can easilyemploy thejconstruction herein specifically shown, asto alltwelve-toothed ratchets 69, which (as shown in Fig. 3) meshdirectly-with the .pinions 107 corresponding therewith; but to preventinterference with the movement of the relatively wide dead pawls .73 and73 which must be provided for thetentoothed ratchets 69 and-69, Iprovide on the sides of the rosette 68 68 opposite the ratchets 69 and69, ten-toothed gears 108 and 108 'with which mesh the correspondinglytoothed gears 107 and 107 For givin aCCSSJIQ the display Wheels 106 Iprovide aslide 108in the front of the head 40,

and as a reading guide I provide a bar 109 to which the displaywheels106 are so related that when a number on the wheel alines with the bar109 the corresponding number on the impression rosette is presented inprinting position with respect to the orifice 66 in the frame 60.

While for some of the purposes of m'yinvention any suitableinking devicemay be employed I preferably provide a novel inkmg arrangement employ nga ribbon in association with an ink supply roller, and arrange saidribbon to 'be continuously fed unidirectional rotation of a drivingroller..

, 'In the drawings 101 indicates an endless inking ribbon passing indouble'ply beneath the impression surfaces 65, 65 over an idle guidingroller 111, mounted on a transverseshaft 112, at the forward end of theframe shown.

60, and over an ink-impregnated reservoir roller 113 mounted fix edlyona shaft 114 at the rear end of the frame. The shaft 112 is mounted foreasy detachmentin the frame, to

this end being seated at one end in a slot 1. .5

vided with a knurled thumb piece 122, Formaintaining the ribbon 111 tauta tension 123 guided in slots 125in the sides of the frame and acted onby convenient tension springs 126, to press it constantly against theribbon. For automatically shifting the ribbon with each down-stroke ofthe movable element 21, I provide on one end of the shaft 114 a ratchet127 arranged preferably outside of the frame member 61, and I disposefor cooperation therewith a pawl bar 128, extending transversely acrossthe frame, at one end 'pivotallyfmounted in the frame member 61, asshown at 129, and at its other end extending from the slot 130, whichacts as a guide to permit the reduced end of the pawl bar 128 tocooperate with a few of the uppermost teeth of the ratchet 127. A link131 connects the pawl bar 128 between its end with the cross bar 50,carried by the lug 24 of the base above the pivot screws 25 on which thestamping element oscillates. Such eccentricity of the fixed point ofattachment of the link 131 causes the oscillation of the stamping member21 to advance and retract the'pawl bar 28 so as to feed the forwardratchet 27 and the connected inking cylinder 113 which thus feeds theribbon 110 every time the stamping element is oscillated. This form ofdrive may obviously be used, however, with movable inkingmechanismsother than the ribbon feed In brief resume of the operation of thestamp, it will be understood that the electromagnet or other motorcooperating with springs 104 receiving an impulse from. an electricclock each minute, impart to the arm 92 a fore and aft movement everyminute, which movement serves positively to impart'to the shaft 97 anddisk 98am oscillation which operates to depress the yoke 80, throwinto'action pawls 85 as are permitted to act upon the ratchet 69, andthen to raise the yoke 80 which through the ratchet and pawl connectionadvances one or more of the impression rosettes, and then to throw thepawls out'of engagement with the active roller 124 is provided, mountedon a shaft 'ratchets, permitting the dead-pawls 7 3 for the ratchets andthe frictionpawl 89 for the yoke to automatically aline the printingrosettes and bring the yoke to normal position. Each advance movement ofan impression rosette correspondingly advances the display rosette 106associated therewith, and at any time the position of the rosettes maybe ascertained or manuallyv set through the agency of. such displayrosettes 106;, To make a stamping impression the moving element 21 isdepressed, its depression serving to operate'the ribbon feed mechanismand to. bring the impression members down upon the platen surface 22.Such depression has no functional effect on the rosettmoving mechanismon account of the proximity-of pivot points 35 and 25.

While I have herein described in some dewhich I believe to be new inmany of its .details of construction and arrangement, it

will be understood that in its broader'aspect my invention may beembodied in machines Widely different in details of construction andarrangements of parts from that herein illustrated within the scope ofthe appended claims.
